JOHN C. HINGE, OF BRIDGEBORT, CONNECTICUT, ASSIGNOR TO THE SING-EB MANU-FACTURING COMPANY,

GEARING.

A CORPORATION OF NEW JERSEY.

Patented Jan. 16, 1912 Application filedJ'uly 14, 1910. Serial No.571,885.

To all whom it may concern:

Be it known that I, JOHN C. RINGE, a citizen of the United States,residing at Bridgeport, in the county of Fairficld and State ofConnecticut, have invented certain new and useful Improvements inGearing,

which the following is a specification, reference being had therein tothe accompany-- ing drawings.

This invention relates to improvements in sewing machines and hasparticular reference to the means employed for manually determining thevertical position of the needles with respect to the fabric when thesewing machine is at rest.

In the manufacture of certain classes of productions, it is desirable tomount the sewing machine head with its front end facing the operator,and when the frame is of the ordinary length 'ployed hand or belt wheelmounted upon I the rear end of the needle-driving shaft is so farremoved .manua'l manlpulation ard and belt wheel.

bevel gear -4 the hand wheel provided 1 represents the commonly-employedmain or needle bar-actuating shaft,.2 a bevel gear wheel orpower-transmitting member car-' ried by said shaft, 3 the hand wheelshaft, with a hub 5 and secured by screw 6 upon the shaft 3, the latterat its inner end being mounted in a bearing 7 formed in a boss 8, whichlatter in the present instance is cast integral with the sewing machinebracket arm 9, the hub 5 being mounted .in the tubular portion 10 of theboss 8. Carried by the shaft 3 is a wheel or power-transmitting member11 which at the will of the operator,

and the arm standard of the ordinary height the commonly-emthrough themanipulation of the hand wheel 4, is caused to mesh with the member 2 toturn the shaft 1. i 1

Located inside of the bracket arm is a catch lever 12 pivoted upon ascrew 13, the rear end of said lever having .secured to it one end of achain connection 14, the opposite end of which latter is connected witha suitable foot treadle 20, a spring 15 normally acting to hold the freeend 16 lever downward.

17 is a spring mounted upon the shaft 3 with its inner'end seatedagainst the wall 18 of the bearing 7, the opposite end of said springacting upon the inner end of the hub 5 to normally hold'the member 11out of engagement with the member 2. v

The arrow .9 indicates the direction of the feed of the material.

While a preferred form of wheel for operatively connecting the mainshaft with the hand wheel shaft is herein shown, it will be evident thatthe commonly-employed powertransmitting friction disks might besubstituted therefor, and that the gear carried by the main shaft mightcomprise the adjustable power-transmitting element instead of the gearcarried by the hand wheel shaft, Without materially afiecting theutility of the improved mechanism, the gist of the in- ,vention lying inproviding said main shaft with temporarily connected means for-rotatingit independent of its .belt driven pulley.

In the operation of the device, supposing the parts to occupy thepositions shown in the drawing and it is desired tocommence thestitching operation, the operator rocks the lever 12, in opposition tothe spring 15, which removes the end 16 of the catch lever fromengagement with the Wall 19 of the member 11, thus permitting the spring17 to disengage the member 11 from engagement with the member 2, whichreleases the manually-controlled mechanism from engagement with theactuating mechanism of the sewing machine during the stitchingoperation. Then the machine is again brought to rest and it is desiredto register the needle at a point different from that at which it wasbrought to rest, the operator, througluthe manipulation of the handwheel 4, moves the member 11 into operative relationship with of saidcatch the member 2 Where it is held by the end 16 of the lever 12 actingagainst the wall 19 ofhe member 11, as shown in the drawing.

laim:

In a power-transmitting mechanism, a ro-' tary main-shaft, a rotaryhand-Wheel shaft havingits axis of rotation in a direction transverse tothe axis of said main-shaftand having sliding movements in the directionof its length, power-transmitting members one of which is carried bysaid main-shaft,

its coacting member being carried by said hand-Wheel shaft, a latchforholding said transmitting members in engagement, and means including aspring and a treadle for 15 discontinuing the engagement of saidpowertransmitting members.

In testimony whereof, I have slgned my name to this specification, inthe presence of two subscribmg Witnesses.
